- An extension spring 323 _ 4 is disposed in the helical gear 323 _ 2 , and supports a torque of the helical gear 323 _ 2 and an external force applied to the helical gear 323 _ 2 .
- a friction pad 323 _ 5 is placed between the helical gear 323 _ 2 and the spur gear 323 _ 3 , and spatially separates the helical gear 323 _ 2 and the spur gear 323 _ 3 .
- a motive power of the motor 310 is transferred to the clutch gear 323 by gear coupling between the worm gear 321 installed in the end of the driving shaft 311 and the clutch gear 323 .
- the helical gear 323 _ 2 and spur gear 323 _ 3 configuring the clutch gear 323 transfer a motive power to the complex gear 324 while rotating integrally by a frictional force that is generated by the friction pad 323 _ 5 .
- the helical gear 323 _ 2 disposed in the upper portion of the clutch gear 323 and the helical gear of the complex gear 324 are disposed to be separated from each other, and the spur gear 323 _ 3 disposed in the lower portion of the clutch gear 323 and the spur gear of the complex gear 324 are coupled to each other to transfer a motive power.
- the helical gear disposed in an upper portion thereof and the spur gear disposed in a lower portion thereof are coupled integrally and simultaneously rotate with respect to the same shaft.
- a motive power in the clutch gear 323 is transferred to the spur gear, and thus, the helical gear rotates simultaneously with the spur gear.

- the second gear set 340 includes the helical gear 341 that is installed to be rotatable through gear coupling with the helical gear configuring the complex gear 324 , and the spur gear 342 that is fixed and coupled to the helical gear 341 to rotate simultaneously with the helical gear 341 .
- a motive power transferred to the complex gear 324 is transferred to the second gear set 340 through gear coupling between the helical gear configuring the complex gear 324 and the helical gear configuring the second gear set 340 , and thus, the second gear set 340 and the rotational shaft 330 are coupled integrally and rotate simultaneously.

- a rotational motion generated by the motor 310 is transferred to the outer gear 210 and the inner gear 220 by the spur gear set 350 and 360 .
- the outer gear 210 and the inner gear 220 change the rotational motion to a rectilinear motion and thus ascend/descend in a vertical direction with respect to the body housing 10 , respectively.
- the spur gear set 350 and 360 is configured with first and second spur gears 350 and 360 that are provided to have different diameters.
- the diameter of the first spur gear 350 is greater than that of the second spur gear 360 , and is coupled in engagement with the spur gear teeth 211 that is provided inside the outer gear 210 .

- the rotary sensor 40 is coupled to the spur gear of the second gear set 340 that is driven integrally with the rotational shaft 330 , and thus is rotation-driven identically to the rotational shaft 330 .
- the motive power of the motor 310 is transferred to the rotational shaft 330 as-is, and thus, the rotational shaft 330 also rotates in the rotational direction of the motor 310 .
- the rotary sensor 40 rotates identically to the rotational shaft 330 to output a normal state signal.
- the motive power is abnormally transferred, for example, when an external force exceeding a predetermined reference is given to the monitor frame 20 , the motive power of the motor 310 is not transferred to the rotational shaft 330 due to the structural feature of the clutch gear 323 .
- the rotational shaft 330 does not rotate, and moreover, the rotary sensor 40 coupled to the rotational shaft 330 does not rotate. That is, even though the motor 310 is rotating, when the rotary sensor 40 does not rotate, this is determined as an abnormal state by the rotary sensor 40 , and thus, the rotary sensor 40 outputs an abnormal state signal.
- the normal or abnormal state signal outputted from the rotary sensor 40 is transmitted to the PCB, which is configured with the controller and power source of the motor 310 , through an internal electric line.
- the controller outputs a control signal that allows the rotational direction of the motor 310 to be switched to a reverse direction, according to the sensing signal.
- the controller controls the rotational direction of the motor 310 according to state information regarding whether the rotational shaft 330 rotates and state information regarding whether the motor 310 rotates, and its detailed description will be described below.
- the motor 310 and the rotational shaft 330 rotate together.
- the controller which receives state information regarding whether the rotational shaft 330 rotates and state information regarding whether the motor 310 rotates, determines an external force as being given to the pop-up monitor and controls the motor 310 to rotate in a reverse direction with respect to the original rotational direction. That is, while the monitor frame 20 is ascending, when an external force is applied to the pop-up monitor, the controller controls the rotational direction of the motor 310 in a reverse direction in order for the monitor frame 20 to descend. While the monitor frame 20 is descending, when an external force is applied to the pop-up monitor, the controller controls the rotational direction of the motor 310 in a reverse direction such that the monitor frame 20 ascends.
- the motor 310 in a state where the monitor frame 20 has ascended to the maximum with respect to the body housing 10 , when an external force is applied to the pop-up monitor, the motor 310 is in a stopped state, but the rotational shaft 330 may rotate by the external force.
- the controller when the controller receives state information indicating that the rotational shaft 330 is rotating when the monitor frame 20 has been opened and state information indicating that the motor 310 does not rotate, the controller controls the rotational direction of the motor 310 in a direction where the monitor frame 20 descends.
- the state information regarding the rotation of the rotational shaft 330 has been described as being obtained from the sensing signal of the rotary sensor 40 , but the spirit and scope of the embodiments are not limited thereto. The spirit and scope of the embodiments should be construed as including other elements for obtaining the state information regarding the rotation of the rotational shaft 330 .
- a damping spring 13 for supporting the vertical motion of the rack gear set 27 may be disposed in each of both sides of the body housing 10 .
- the rack gear set 27 receives the motive power of the motor 310 though gear coupling with the spur gear set 350 and 360 of the driving unit 30 .
- a gap is formed between the spur gear and the rack gear, and consequently, when the monitor frame 20 ascends/descends, shaking occurs in proportion to the gap. Also, rattle noise is caused by the shaking of the monitor due to the vibration of the vehicle.
- the pop-up monitor is characterized by including the damping spring 13 that supports the vertical motion of the rack gear set 27 .
- the damping spring 13 is disposed in each of the both sides of the body housing 10 , and configured with a case-damping spring 13 _ 1 and a torsion spring 13 _ 2 .
- a groove 212 is formed along a length direction, at an outer surface of the outer gear 210 of the rack gear set 27 .
- the damping spring 13 applies a constant pressure to the outer gear 210 along the groove 212 .
- the torsion spring 13 _ 2 of an elastic material applies a constant moment to the case-damping spring 13 _ 1 when assembled with the case-damping spring 13 _ 1 . Due to the moment, the damping spring 13 continuously applies a constant pressure to groove 212 that is formed at the outer surface of the outer gear 210 .
- the pressure applied from the damping spring 13 removes a gap between the rack gear set 27 and the spur gear set 350 and 360 , and thus, shaking is prevented from occurring when the monitor frame 20 ascends/descends.
- the vertical motion of the monitor frame is supported by the rack gear set, which includes the outer gear that is fixed and coupled to the monitor frame to directly induce the vertical motion of the monitor frame, and the inner gear that is received in the internal space through rail coupling with the outer gear.
- the rack gear set is characterized by having the double rack gear structure of the outer gear and inner gear.
- the inner gear is not directly associated with the vertical motion of the monitor frame, but when the inner gear ascends simultaneously with the outer gear and then the outer gear has ascended to the maximum, by maximizing a portion overlapping with the outer gear, the inner gear can support forward and rearward/right and left shaking that occurs in the outer gear.
- the receiving space for receiving portable equipment or the like is formed in the body housing, and a connector, a USB port, etc. for supplying a power to the portable equipment or communicating with the portable equipment are provided in one side of the body housing, thus enhancing a user's convenience.
- the pop-up monitor includes the photo sensor, and thus, when an obstacle such as a person's hand or an object lies in the receiving space that is formed in the body housing, by sensing the obstacle and controlling the monitor to be driven in a reverse direction, an accident can be prevented from being caused by the motion of the monitor.
- the monitor when an external force is applied to the monitor while the monitor is being maintained in an opened state, by sensing the external force and allowing the monitor to be automatically opened/closed, the monitor can be prevented from being damaged by the external force.

Abstract
Description
- This application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 10-2011-0074182, filed on Jul. 26, 2011, the disclosure of which is incorporated herein by reference in its entirety.
- The present disclosure relates to a pop-up monitor with an obstacle sensing function, and in particular, to a pop-up monitor with an obstacle sensing function, which performs an avoidance operation when an obstacle is sensed.
- Recently, as the functions and quality of vehicles are highly enhanced, various monitors for controlling an air-conditioning apparatus, a navigator, a Liquid Crystal Display (LCD) television (TV), etc. are installed in the vehicles. Such monitors are categorized into rear monitors and front monitors. The rear monitor is disposed in the rear of a driver's seat or a console and operated by a passenger of a back seat. The front monitor is installed on a display panel in front of a vehicle body and operated by a passenger of a front seat such as a driver's seat or a passenger seat.
- The front monitor mounted on the display panel is configured such that a frame with a monitor mounted thereon is popped up in order for a driver to more easily look at the front monitor. As such pop-up types, there are a pop-up type where the monitor frame is vertically popped up, a pop-up type where the monitor frame is popped up while rotating, and a pop-up type where the monitor frame moves horizontally and then is popped up while rotating vertically.
- Among such pop-up types, the pop-up type where the monitor frame is vertically popped up is illustrated in
FIG. 1 . -
FIG. 1 is a partially cut rear view illustrating an operation of a related art electric pop-up monitor for a vehicle. - Referring to
FIG. 1 , a related art electric pop-up monitor 1 for a vehicle includes a body 3 mounted on one side of a crush pad of a vehicle, a monitor 4 disposed in the body 3, and a driver 5 that lifts and drops the monitor 4 with respect to the body 3. - That is, a guide protrusion 6 being a guide that allows the monitor 4 to ascend and descend with respect to a space portion formed inside the body 3 is lengthily formed upward and downward to protrude in an internal direction from one side of the body 3. Such a guide groove 7 coupled to the guide protrusion 6 is formed in one side of the monitor 4.
- The driver 5 is disposed between the body 3 and a rear surface on the reverse of a portion forming a screen 8 in front of the monitor 4. Herein, the driver 5 includes a motor 9 generating a torque, and a plurality of gears such as a driven
gear 10 transferring the torque of the motor 9. Aworm gear 11 is disposed in a rotational axis of the motor 9, and aworm wheel gear 13 is disposed in a drivenshaft 12 interlocking with the drivengear 10. A pinion gear 14 coupled to the drivengear 10 rotates about a pinion axis 15. In this case, the pinion axis 15 and the drivenshaft 12 are supported in one side of the body 3. Furthermore, arack gear 17 where aspur gear 16 is vertically formed is disposed in a rear surface of the monitor 4. - As described above, a related art pop-up monitor drives a monitor upward and downward by gear-coupling with the spur gear that is formed in the pinion gear and the rack gear, and the monitor that has completely ascended in an upper direction with respect to the body is supported by gear engagement. In this case, since a portion supporting the ascended monitor is narrow, the monitor is easily shaken upward and downward or from side to side by vibration that occurs in driving a vehicle.
- Moreover, in the related art, since the spur gear formed in the rack gear is exposed to the outside, there is much possibility that the driving of a vehicle is failed due to foreign substances.
- Moreover, even though an obstacle such as a person's hand or other objects lies on a route through which a monitor moves vertically, since the related art monitor cannot have a function of sensing the obstacle, a user's hand or an object is caught due to a closed monitor.
- Moreover, while a monitor is being maintained in an opened state, when an external force is applied to the monitor, there is high possibility that the monitor is damaged because a portion supporting the forward and rearward movement of the monitor is narrow. Accordingly, a new type of technology having a function of preventing the damage of a monitor is required.
- Accordingly, the present disclosure provides a pop-up monitor with a double rack gear structure, which allows the vertical driving of a monitor to be performed by an internally touched double rack gear that is disposed in each of both sides of the monitor, and thus increases a support power to the monitor when the monitor has ascended to the maximum with respect to a body.
- The present disclosure also provides a pop-up monitor in which a receiving space for receiving portable equipment is formed in a body.
- The present disclosure also provides a pop-up monitor which senses an obstacle and performs an avoidance operation, when the obstacle lies on a moving route of a monitor.
- The present disclosure also provides a pop-up monitor which senses an external force and allows a monitor to be automatically opened/closed, when the external force is applied to the monitor.
- The object of the present invention is not limited to the aforesaid, but other objects not described herein will be clearly understood by those skilled in the art from descriptions below.

- When the controller receives a sensing signal, indicating that the rotational shaft does not rotate, from the sensor and receives state information indicating that the motor is rotating continuously, the controller may control the rotational direction of the motor in a reverse direction.
- In a state where the monitor frame has been opened, the controller may control the rotational direction of the motor in a direction where the monitor frame descends, when state information, indicating that the rotational shaft is rotating and the motor does not rotate, is received from the sensor.

-
FIG. 2 a andFIG. 2 b are a perspective view illustrating a pop-up monitor with a double rack gear structure, according to an embodiment of the present invention. - Referring to
FIG. 2 a andFIG. 2 b, the pop-up monitor according to an embodiment of the present invention includes abody housing 10 that is received in a crash pad mounted on the front inside a vehicle, amonitor frame 20 that is installed to be moved in a direction vertical to thebody housing 10, and a driving unit (illustrated inFIG. 5 ) that is disposed in order for themonitor frame 20 to move in a vertical direction. - The
body housing 10 is received in the crash pad that is installed in a center facia of the front inside the vehicle, and supports themonitor frame 20 such that themonitor frame 20 is shown in a vertical direction on the crash pad. - The inside of the
body housing 10 is empty, and thus, thebody housing 10 secures a space for receiving portable equipment such as a Personal Digital Assistant (PDA), an MP3 player, and a mobile communication terminal. Aconnector 11 for supplying a power to the portable equipment is provided in one end of thebody housing 10. - A Universal Serial Bus (USB) port enabling communication with the portable equipment may be provided in one end inside the
body housing 10. - By coupling a screw (not shown) to the crash pad with a
coupling part 12 that is formed to protrude in each of both sides of thebody housing 10, thebody housing 10 may be fixed to the crash pad. - The
monitor frame 20 is installed to be moved in a direction vertical to thebody housing 10. Themonitor frame 20 includes acase 23 that is coupled to a rear side of amonitor 21 to support themonitor 21, and asupport frame 25 that is coupled to a rear side of thecase 23 to support a vertical motion of thecase 23. - The
support frame 25 is fixed to thecase 23 through screw coupling with the rear side of thecase 23, and includes a wing-shaped coupling member 25_1 that is formed to protrude in each of both sides of thecase 23. - Moreover, the
monitor frame 20 may further include a rack gear set 27 that induces a vertical motion of themonitor frame 20 by sliding in a vertical direction with respect to thebody housing 10. The rack gear set 27 may be fixed to the coupling members 25_1 that are respectively formed to protrude in both sides of thesupport frame 25, through screw coupling. - In the embodiment, the rack gear set 27 includes an outer gear that is fixed and coupled to the coupling members 25_1 to support the vertical motion of the
monitor frame 20, and an inner gear that is received inside the outer gear to support a vertical motion of the outer gear through rail coupling with the outer gear. The rack gear set 27 will be specifically described below with reference toFIGS. 3 to 5 . -
FIG. 3 is a front-sectional view schematically illustrating a rack gear set according to an embodiment of the present invention.FIG. 4 is a top-sectional view schematically illustrating a rack gear set according to an embodiment of the present invention.FIG. 5 is a perspective view schematically illustrating a rack gear set according to an embodiment of the present invention. - The rack gear set 27, as illustrated
FIGS. 3 to 5 , includes anouter gear 210, aninner gear 220, and aguide shaft 230. - The
outer gear 210 is installed in each of both sides of themonitor frame 20. Theouter gear 210 is fixed to the coupling member 25_1 of thesupport frame 25 through screw coupling and operates integrally with themonitor frame 20. - The
outer gear 210 has a -shape with an internal space. Aspur gear teeth 211 is formed in one row along a length direction, in one side inside theouter gear 210. In this case, thespur gear teeth 211 is coupled to a first spur gear of a driving unit 30 (which will be described below with reference toFIG. 7 ) to change a first rotational motion, transferred through the first spur gear, to a first rectilinear motion, thereby enabling the vertical motion of themonitor frame 20 that is fixed and coupled to theouter gear 210. - Moreover, a rail groove is formed along a length direction in one end inside the
outer gear 210, and the below-describedinner gear 220 supports a vertical motion by sliding in a vertical direction along the rail groove. - The
inner gear 220 is placed in an internal space of theouter gear 210, and arail 221 is formed along a length direction, in one end of theinner gear 220. In this case, therail 221 may be inserted into the rail groove, and a vertical motion of theinner gear 220 is supported through rail coupling between the rail groove of theouter gear 210 and therail 221. - Moreover, a
spur gear teeth 223 is formed along a length direction even in one side inside theinner gear 220. Thespur gear teeth 223 is coupled to a second spur gear of the driving unit 30 (which will be described below with reference toFIG. 7 ) to change a second rotational motion, transferred through the second spur gear, to a second rectilinear motion, thereby enabling the vertical motion of theinner gear 220. - The
guide shaft 230 is inserted into a throughhole 225 that is formed in theinner gear 220, and guides a vertical motion of theinner gear 220. Theguide shaft 230 supports theinner gear 220 from forward and rearward/right and left shaking that occurs when theinner gear 220 ascends. - According to the embodiment, as described above, the vertical motion of the
monitor frame 20 is supported by the rack gear set 27, which includes theouter gear 210 that is fixed and coupled to themonitor frame 20 to directly induce the vertical motion of themonitor frame 20, and theinner gear 220 that is received in the internal space through rail coupling with theouter gear 210. - That is, in the embodiment, the rack gear set 27 rack gear set is characterized by having the double rack gear structure of the
outer gear 210 andinner gear 220. Herein, theinner gear 220 is not directly associated with the vertical motion of themonitor frame 20, but when the inner gear ascends simultaneously with theouter gear 210 and then theouter gear 210 has ascended to the maximum, by maximizing a portion overlapping with theouter gear 210, theinner gear 220 can support forward and rearward/right and left shaking that occurs in theouter gear 210. - Moreover, one or
more photo sensors 29 may be further disposed in a lower end of themonitor frame 20. The photo sensor includes a light emitting part and a light receiving part. Herein, the light receiving part receives light emitted from the light emitting part, and thus, the photo sensor detects whether an object exists on a corresponding path. - In the embodiment, when an obstacle (for example, a person's hand, and other objects) is in a receiving space formed inside the
body housing 10 while themonitor frame 20 is descending (i.e., close) from a vertically ascended location with respect to thebody housing 10, the one ormore photo sensors 29 disposed in an lower end of themonitor frame 20 senses the obstacle. - A sensing signal detected by the
photo sensor 29 is transmitted to a Printed Circuit Board (PCB), including a controller and power source of the below-describedmotor 310, through an internal electric line. The controller switches the rotational direction of themotor 310 to a reverse direction to again lift themonitor frame 20, according to the sensing signal. - As an embodiment, in order to prevent an error from occurring in sensing an obstacle, a plurality of
photo sensors 29 may be installed in the lower end of themonitor frame 20. Only when obstacle sensing signals more than a predetermined number of obstacle sensing signals are received from the photo sensors 29 (for example, a case where five photo sensors are installed, and sensing signals are received from three or more photo sensors among the five photo sensors), the controller outputs a control signal that allows the rotational direction of themotor 310 to be switched to a reverse direction. - As another embodiment, the
photo sensor 29 senses an obstacle that exists in a lower surface of themonitor frame 20, and delivers a measured distance between the obstacle and the lower surface of themonitor frame 29 to the controller. In this case, the controller may differently control the rotational direction of themotor 310 according to the measured distance. For example, the controller determines whether the measured distance is greater than a predetermined value. When the measured distance is greater than the predetermined value, the controller may output a control signal that allows the rotational direction of themotor 310 to be maintained as-is, but when the measured distance is not greater than the predetermined value, the controller may output a control signal that allows the rotational direction of themotor 310 to be switched to a reverse direction. - According to the embodiment, the pop-up monitor may further include a warning unit that emits warning sound. When an obstacle sensing signal is received from the
photo sensor 29 while themonitor frame 20 is descending, the controller controls the warning unit to be driven, and determines whether a measured distance between the obstacle and themonitor frame 20 is greater than the predetermined value. When the measured distance is greater than the predetermined value, the controller may outputs a control signal that allows a rotational speed of themotor 310 to be reduced, but when the measured distance is not greater than the predetermined value, the controller may outputs a control signal that allows a rotational direction of themotor 310 to be switched to a reverse direction. - The driving unit 30 includes the
motor 310, a first gear set 320, arotational shaft 330, a second gear set 340, and aspur gear set FIG. 5 . -
FIG. 7 is a sectional view illustrating a driving unit according to an embodiment of the present invention. - Referring to
FIG. 7 , the driving unit 30 is provided in thebody housing 10, and is installed on abracket 370 that is provided across an upper portion of thebody housing 10. - The
motor 310 is installed in one end of thebracket 370, and the PCB (not shown) including the controller and power source of themotor 310 is disposed on thebracket 370. - A rotational motion of the
motor 310 is transferred to therotational shaft 330 by the first and second gear sets 320 and 340 that are disposed in thebracket 370. - Herein, the first gear set 320 includes a
worm gear 321 that is disposed in an end of a drivingshaft 311 in themotor 310, aclutch gear 323 that is coupled to theworm gear 321, andcomplex gear 324 that is coupled to theclutch gear 323. -
FIG. 8 is a view illustrating an internal detailed structure of a clutch gear according to an embodiment of the present invention. - Referring to
FIG. 8 , theclutch gear 323 is a complex gear that is configured with a helical gear 323_2 disposed in an upper portion of a shaft 323_1, and a spur gear 323_3 disposed in a lower portion of the shaft 323_1. - An extension spring 323_4 is disposed in the helical gear 323_2, and supports a torque of the helical gear 323_2 and an external force applied to the helical gear 323_2. A friction pad 323_5 is placed between the helical gear 323_2 and the spur gear 323_3, and spatially separates the helical gear 323_2 and the spur gear 323_3.
- A motive power of the
motor 310 is transferred to theclutch gear 323 by gear coupling between theworm gear 321 installed in the end of the drivingshaft 311 and theclutch gear 323. The helical gear 323_2 and spur gear 323_3 configuring theclutch gear 323 transfer a motive power to thecomplex gear 324 while rotating integrally by a frictional force that is generated by the friction pad 323_5. In this case, the helical gear 323_2 disposed in the upper portion of theclutch gear 323 and the helical gear of thecomplex gear 324 are disposed to be separated from each other, and the spur gear 323_3 disposed in the lower portion of theclutch gear 323 and the spur gear of thecomplex gear 324 are coupled to each other to transfer a motive power. - When an external force is applied to the
clutch gear 323 due to an external force given to themonitor frame 20, slidingness occurs in the friction pad 323_5 placed in theclutch gear 323, and therefore, the spur gear 323_3 disposed in the lower portion of theclutch gear 323 cannot receive a motive power from the helical gear 323_2 disposed in the upper portion of theclutch gear 323. - That is, when an external force is applied, the
motor 310 is normally driven, but due to slidingness occurring in the friction pad 323_5, the motive power of themotor 310 is not transferred to thecomplex gear 324, the rotational shaft 30, etc. Such a limitation is sensed by a rotary sensor, and its detailed description will be described below. - In the
complex gear 324, the helical gear disposed in an upper portion thereof and the spur gear disposed in a lower portion thereof are coupled integrally and simultaneously rotate with respect to the same shaft. A motive power in theclutch gear 323 is transferred to the spur gear, and thus, the helical gear rotates simultaneously with the spur gear. - The
rotational shaft 330 is configured with the second gear set 340. The second gear set 340 includes thehelical gear 341 that is installed to be rotatable through gear coupling with the helical gear configuring thecomplex gear 324, and thespur gear 342 that is fixed and coupled to thehelical gear 341 to rotate simultaneously with thehelical gear 341. - That is, a motive power transferred to the
complex gear 324 is transferred to the second gear set 340 through gear coupling between the helical gear configuring thecomplex gear 324 and the helical gear configuring the second gear set 340, and thus, the second gear set 340 and therotational shaft 330 are coupled integrally and rotate simultaneously. - The
spur gear set rotational shaft 330. - The
spur gear set rotational shaft 330, and is respectively coupled to engage thespur gear teeth outer gear 210 and a portion of theinner gear 220. - Therefore, a rotational motion generated by the
motor 310 is transferred to theouter gear 210 and theinner gear 220 by thespur gear set outer gear 210 and theinner gear 220 change the rotational motion to a rectilinear motion and thus ascend/descend in a vertical direction with respect to thebody housing 10, respectively. - The
spur gear set first spur gear 350 is greater than that of thesecond spur gear 360, and is coupled in engagement with thespur gear teeth 211 that is provided inside theouter gear 210. Thespur gear 360 is coupled in engagement with thespur gear teeth 223 that is provided inside theinner gear 220. - The
spur gear set rotational shaft 330 to have the same angular velocity, but provides different linear velocities to theouter gear 210 and theinner gear 220. Therefore, theouter gear 210 may have a linear velocity greater than that of theinner gear 230 and ascend/descend in a vertical direction. - As illustrated in
FIG. 7 , arotary sensor 40 that senses the transfer of a motive power from the driving unit 30 may be further disposed on thebracket 370 that is provided across an upper portion of thebody housing 10. - The
rotary sensor 40 is disposed to be separated from thecomplex gear 324 with a certain space therebetween. Therotary sensor 40 is coupled to the spur gear of the second gear set 340 that is driven integrally with therotational shaft 330, and thus is rotation-driven identically to therotational shaft 330. - While the motive power is normally being transferred, the motive power of the
motor 310 is transferred to therotational shaft 330 as-is, and thus, therotational shaft 330 also rotates in the rotational direction of themotor 310. At this point, therotary sensor 40 rotates identically to therotational shaft 330 to output a normal state signal. - When the motive power is abnormally transferred, for example, when an external force exceeding a predetermined reference is given to the
monitor frame 20, the motive power of themotor 310 is not transferred to therotational shaft 330 due to the structural feature of theclutch gear 323. - Therefore, even when the
motor 310 is rotating, therotational shaft 330 does not rotate, and moreover, therotary sensor 40 coupled to therotational shaft 330 does not rotate. That is, even though themotor 310 is rotating, when therotary sensor 40 does not rotate, this is determined as an abnormal state by therotary sensor 40, and thus, therotary sensor 40 outputs an abnormal state signal. - The normal or abnormal state signal outputted from the
rotary sensor 40 is transmitted to the PCB, which is configured with the controller and power source of themotor 310, through an internal electric line. The controller outputs a control signal that allows the rotational direction of themotor 310 to be switched to a reverse direction, according to the sensing signal. - That is, the controller controls the rotational direction of the
motor 310 according to state information regarding whether therotational shaft 330 rotates and state information regarding whether themotor 310 rotates, and its detailed description will be described below. - As an embodiment, while the
monitor frame 20 is ascending/descending in a vertical direction with respect to thebody housing 10, when the motive power is normally transferred, themotor 310 and therotational shaft 330 rotate together. - However, when the motive power is abnormally transferred, the
motor 310 rotates, but therotational shaft 330 does not rotate. In this case, the controller, which receives state information regarding whether therotational shaft 330 rotates and state information regarding whether themotor 310 rotates, determines an external force as being given to the pop-up monitor and controls themotor 310 to rotate in a reverse direction with respect to the original rotational direction. That is, while themonitor frame 20 is ascending, when an external force is applied to the pop-up monitor, the controller controls the rotational direction of themotor 310 in a reverse direction in order for themonitor frame 20 to descend. While themonitor frame 20 is descending, when an external force is applied to the pop-up monitor, the controller controls the rotational direction of themotor 310 in a reverse direction such that themonitor frame 20 ascends. - As another embodiment, in a state where the
monitor frame 20 has ascended to the maximum with respect to thebody housing 10, when an external force is applied to the pop-up monitor, themotor 310 is in a stopped state, but therotational shaft 330 may rotate by the external force. - That is, when the controller receives state information indicating that the
rotational shaft 330 is rotating when themonitor frame 20 has been opened and state information indicating that themotor 310 does not rotate, the controller controls the rotational direction of themotor 310 in a direction where themonitor frame 20 descends. - In the above description, the state information regarding the rotation of the
rotational shaft 330 has been described as being obtained from the sensing signal of therotary sensor 40, but the spirit and scope of the embodiments are not limited thereto. The spirit and scope of the embodiments should be construed as including other elements for obtaining the state information regarding the rotation of therotational shaft 330. - As another embodiment, as illustrated in
FIG. 8 , a dampingspring 13 for supporting the vertical motion of the rack gear set 27 may be disposed in each of both sides of thebody housing 10. - As described above, the rack gear set 27 receives the motive power of the
motor 310 though gear coupling with thespur gear set monitor frame 20 ascends/descends, shaking occurs in proportion to the gap. Also, rattle noise is caused by the shaking of the monitor due to the vibration of the vehicle. - In order to solve limitations such as the shaking of the monitor due to the gap between the gears and noise due to the shaking, in the embodiment, the pop-up monitor is characterized by including the damping
spring 13 that supports the vertical motion of the rack gear set 27. - Specifically, the damping
spring 13 is disposed in each of the both sides of thebody housing 10, and configured with a case-damping spring 13_1 and a torsion spring 13_2. - A
groove 212 is formed along a length direction, at an outer surface of theouter gear 210 of the rack gear set 27. When themonitor frame 20 ascends/descends, the dampingspring 13 applies a constant pressure to theouter gear 210 along thegroove 212. - The torsion spring 13_2 of an elastic material applies a constant moment to the case-damping spring 13_1 when assembled with the case-damping spring 13_1. Due to the moment, the damping
spring 13 continuously applies a constant pressure to groove 212 that is formed at the outer surface of theouter gear 210. - The pressure applied from the damping
spring 13 removes a gap between the rack gear set 27 and thespur gear set monitor frame 20 ascends/descends. - According to embodiments of the present invention, the vertical motion of the monitor frame is supported by the rack gear set, which includes the outer gear that is fixed and coupled to the monitor frame to directly induce the vertical motion of the monitor frame, and the inner gear that is received in the internal space through rail coupling with the outer gear.
- That is, the rack gear set is characterized by having the double rack gear structure of the outer gear and inner gear. Herein, the inner gear is not directly associated with the vertical motion of the monitor frame, but when the inner gear ascends simultaneously with the outer gear and then the outer gear has ascended to the maximum, by maximizing a portion overlapping with the outer gear, the inner gear can support forward and rearward/right and left shaking that occurs in the outer gear.
- Moreover, in embodiments of the present invention, the receiving space for receiving portable equipment or the like is formed in the body housing, and a connector, a USB port, etc. for supplying a power to the portable equipment or communicating with the portable equipment are provided in one side of the body housing, thus enhancing a user's convenience.
- Moreover, the pop-up monitor includes the photo sensor, and thus, when an obstacle such as a person's hand or an object lies in the receiving space that is formed in the body housing, by sensing the obstacle and controlling the monitor to be driven in a reverse direction, an accident can be prevented from being caused by the motion of the monitor.
- Moreover, when an external force is applied to the monitor while the monitor is being maintained in an opened state, by sensing the external force and allowing the monitor to be automatically opened/closed, the monitor can be prevented from being damaged by the external force.
- A number of exemplary embodiments have been described above. Nevertheless, it will be understood that various modifications may be made. For example, suitable results may be achieved if the described techniques are performed in a different order and/or if components in a described system, architecture, device, or circuit are combined in a different manner and/or replaced or supplemented by other components or their equivalents. Accordingly, other implementations are within the scope of the following claims.
